40/80/120 High Speed Probes & Sample Holders
HPD designed and built these high speed probe/sample holders with 40, 80, and 120 lines of UT-47 coax. These probes mount 5 mm, 10 mm and 10x15 mm chips at 4K.
56 Line High Speed Probes
These 56 line high-speed probes were built for 1 cm chips and larger multi-chip modules. These probes incorporate UT-86 coax lines and are used with Z-type liquid Helium cryostats to cool samples to 4K.
